The right side of the side plate 541 is fixedly connected with a torsional spring 542, and the side plate 541 can press the torsional spring 542 in the process of rotation, so that the torsional spring 542 can store elastic potential energy, and then give the side plate 541 a force in the opposite direction for resetting.

[0033] Please refer to the accompanying drawings Figure 5 , the accompanying drawings Figure 7 and the accompanying drawings Figure 8 , the left end of the connecting disc 51 is fixedly connected with a fixed plate 55 inside, and the fixed plate 55 is fixed through welding, thereby providing support for the fixed plate 55. The bottom end of the torsional spring 542 is fixedly connected with the right side of the fixed plate 55, and the torsional spring 542 is fixedly connected, so that the torsional spring 542 is uniformly stressed. The rear side of the sliding column 52 is fixedly connected with a limiting plate 56, and the sliding column 52 transmits the rotating force to the limiting plate 56. The left and right ends of the connecting disc 51 are slidingly connected with hook-shaped plates 57, and the two hook-shaped plates 57 can slide into the inside of the connecting disc 51 for installation through the limitation of the connecting disc 51.

The outer part of the limiting plate 56 is slidingly connected with the proximal ends of the two hook-shaped plates 57, and the limiting plate 56 is clamped by rotating into the inside of the hook-shaped plate 57.

[0034] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 4 and the accompanying drawings Figure 6The crossarm 4 is internally slidably connected to a plurality of protective assemblies 6, which are used to restrict the cables. Each of the plurality of protective assemblies 6 includes a plurality of sliding plates 61. The exterior of the plurality of sliding plates 61 is slidably connected to the interior of the crossarm 4. The restriction of the crossarm 4 allows the sliding plates 61 to slide stably, and three sliding plates 61 form a group. The proximal sides of the plurality of sliding plates 61 are fixedly connected to curved plates 62, which are fixed by welding to provide support for the curved plates 62 and to support the cables. The distal sides of the plurality of sliding plates 61 are fixedly connected to I-shaped plates 63, which are fixed by welding to provide support for the curved plates 62. The I-shaped plates 63 are internally rotatably connected to a connecting plate 64, which slides against the curved plates 62, and then pushes the I-shaped plates 63 to slide, and finally pushes the connecting plate 64 to rotate. The outer parts of the two connecting plates 64 are connected to the transmission plate 65 for rotation, which is rotated by the two connecting plates 64 and then slides against the transmission plate 65;

[0035] The transmission plate 65 is slidably connected to a guide rod 66, which guides the sliding movement of the transmission plate 65. The exteriors of the guide rods 66 are fixedly connected to the two crossbeams 4 and secured by welding, providing support for the guide rods 66. The exterior of the guide rods 66 is sheathed with the inner wall of a spring 67, which constrains the spring 67 and ensures uniform force on the spring 67. One end of the spring 67 is fixedly connected to the interior of the transmission plate 65. As the transmission plate 65 slides, it compresses the spring 67, allowing the spring 67 to store elastic potential energy, which in turn applies a force in the opposite direction to reset the transmission plate 65. The exteriors of the transmission plate 65 are slidably connected to the interiors of the two crossbeams 4. The restraint of the crossbeams 4 ensures stable sliding of the transmission plate 65. The other ends of the springs 67 are fixedly connected to the inner walls of the two crossbeams 4, securing the spring 67 to ensure uniform force on the spring 67.

[0036] Working principle: First, fix the cement pole 1 in the preset position, and then install multiple reinforcement legs 2 at the bottom of the cement pole 1 by welding, ensuring that the reinforcement legs 2 can firmly support the cement pole 1 to prevent it from tilting, and then insert the hook-shaped plates 57 on the two cross beams 4 into the left and right ends of the connecting plate 51 respectively. At this time, hold the grip plate 53 and apply a rotating force, which then drives the sliding column 52 to rotate, and then drives the limit plate 56 to rotate to vertical. At the same time, the sliding column 52 will also drive the side plate 541 to rotate and squeeze the torsion spring 542, so that the torsion spring 54 2 can store elastic potential energy, and then give the sliding column 52 a force in the opposite direction to rotate, and then drive the limit plate 56 to rotate and reset. When the two hook-shaped plates 57 are completely inserted into the interior of the connecting plate 51, the force of the gripping plate 53 is released, and the restoring force of the torsion spring 542 is transmitted to the limit plate 56, so that the limit plate 56 rotates to a horizontal position and is inserted into the interior of the two hook-shaped plates 57, thereby completing the splicing of the two cross beams 4, making it possible to sort more cables and avoid too many cables being entangled and causing installation hazards;

[0037] Then, hold the rotating plate 32 and rotate it, then hold the opening plate 31 and rotate it, so that the rotating plate 32 can be rotated to an angle, and then the opening plate 31 is rotated to a horizontal position. At this time, the connecting plate 36 and the opening plate 31 are simultaneously inserted into the interior of the cement pole 1, and then the connecting column 34 is slid into the interior of the opening plate 31 and the connecting plate 36, and the two nuts 35 are respectively screwed on the upper and lower ends of the connecting column 34 and respectively against the opening plate 31 and the connecting plate 36, and then it can be fixed, while increasing the supporting force, thereby improving its flexibility;

[0038] Then the connecting line is passed through the hole opened inside the crossbeam 4, and when the cable is blown by the wind, it will press against the curved plate 62. At this time, the curved plate 62 will push the sliding plate 61 to slide, and then drive the connecting plate 64 to rotate, and then push the transmission plate 65 to slide. At this time, the transmission plate 65 will slide along the guide rod 66 and squeeze the spring 67, so that the spring 67 can store elastic potential energy, and then can reduce the friction of the cable and absorb the vibration caused by shaking, thereby extending its service life.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
